Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(6,10)(7,11)(8,12)(13,14)(15,19)(16,23)(17,25)(18,21)(20,22)(24,27)(26,28);(1,2)(3,4)(5,6,9,7)(8,11,12,10)(13,15,18,17)(14,19,21,25)(16,22,24,26)(20,27,28,23);(2,4)(13,16,18,24)(14,20,21,28)(15,22,17,26)(19,27,25,23);(5,7,9,6)(8,10,12,11)
